Looking for the simplest way to connect a Sound Blaster to a Raspberry pi with a MT-32 hat . What I understand is there are basically two ways, 1) use a buffer and two resistors and 2) just use resistors and skip the buffer entirely. So just to confirm everything is okay, this schematic is correct, yes?
Also, does anyone know which side +5 is on the MIDI IN on the pi hat, A or B? The DB15 is idiot-proof as it's symmetrical, but the DIN 5 in the schematic can either be seen from the soldering side or looking into the male connector side, for which it would be mirrored. Should be the same on all MIDI IN devices. Googling this was surprisingly inconclusive. I don't want to fry anything.
